Gear set install
The rear wheel hub motor uses a traditional freewheel type sprocket/gear set. This is very
common and you bike will generally either have this type, or a splined cassette type. Whilst it
is possible to remove your bikes existing freewheel, we strongly urge customers to purchase
a new free wheel from us or anywhere else that stocks freewheel gear sets.
Freewheels are considered to be a ‘one time’ only installation. Once they are fastened, they
can be very dicult to take o and transfer to another bike. It’s a relatively inexpensive
part and will save you time and money in the long run, to purchase a new one with your
conversion kit. We stock these freewheels online and instore for your convenience. You don’t
need any special tools to screw on and tighten the freewheel, as the act of pedaling tightens
the freewheel by design.
First step is to locate the spacer that is used to space the freewheel away from the hub. This
isn’t essential for 1, 6 or 7 speed gear sets, but it’s recommended. Once you’ve located the
small silver spacer (shown below) you can screw on (clockwise) the freewheel gently, taking
care not to cross thread the hub or gear set.
Just a note on gear sets. We stock 1, 6, 7, 8 and 9 speed freewheels. There is not enough
width in the rear forks for a 10 speed or more. For customers that are using a 10 speed or
more, you can get away with using the same shifters and adjust your dérailleur so that you
get the correct amount of travel from chain ring 1 to 9. Another option is to purchase a 9
speed shifter which is very aordable. For anyone that isn’t satised with a comprise on gear
sets to make space for a 1,000W hub motor (which is completely changing the entire bike),
then this kit is not for you.
For those with disk brakes, the disk brake rotor
installs onto the side of the motor hub just like a
regular hub.
You can use the existing bolts that are already
installed into the side of the hub. Simply loosen
the bolts, remove the black plastic spacer and
install your disk rotor.
Tighten the bolts as shown to maximum 5Nm (40
lbs) tightening torque. If you overtightened these
bolts, you may risk stripping the hub which is
not covered by warranty. If you’re not using disk
brakes, you can leave the bolts and spacer as they
are, or remove them completely. If you remove
the plastic spacer and tighten up the bolts without
a disk in place, the motor won’t spin freely.
If you don’t have disk brakes, you can leave this
side of the hub untouched.
